To improve the efficiency of solar power generation by concentrating light, there have been some technical attempts at home and abroad, such as the Chinese utility model patent "photovoltaic power generation device", publication number CN206135764U, which includes multiple rows of brackets, and the inclination of each row of brackets toward the sun Photovoltaic modules are installed on the surface, and a reflector is installed above the brackets in each row. The angle between the reflector and the horizontal plane is between 60 and 90°, which is used to reflect sunlight to the light-receiving surface of the photovoltaic modules. The plate is hinged on the top of the bracket; by arranging the reflective plate above each row of photovoltaic modules, the power generation per unit area is improved, but this structure increases the height of the bracket, so that the modules in the front and rear rows can still be maintained on the winter solstice. For 6 hours without blocking, the distance between the front and rear rows has to be increased; at the same time, reflectors are added in the height direction, which is easy to cause the danger of the photovoltaic power generation device toppling in the case of strong wind. Usually, photovoltaic power generation sites are mostly open areas or high places, and the wind speed and wind force are relatively large. How to effectively and safely realize the concentrating of reflectors is an exploration direction to effectively improve the utilization efficiency of photovoltaic power generation resources.
